is shawn els-3, the meeeing ends of the fL-e normally held in engaging position by means of a spring 12, which bears on the free end gr tail of said bolt, as clearlyshown in r pproximately half the outer peripheral wall for the shuttle is hinged to open outwardly therefrom to permit the-insertion o'tl wrapping material X in the folded half, as shown in Figl 2. For this purpose short hinge sections 13, are engaged upon 4each of the pintlcs 6, and are each connected by means of pintles 14, with longer peripheral wall sections 15 and 1G, respectively. The section 15, is provided with a tongue 17', adapted to pass through a corresponding slot in the outer end of the peripheral wall section 16, and to rest upon a transverse bar 18, secured across lsaid slot ou the inner side of said wall section at the extremity thereof.

A bolt 19, is slidahly engaged on the inner side ot' saidwall section 16. and at its outer end is curved outwardly and upwardly to engage over the tongue 17, on the plate 15. As shown, pulling springs 20, are secured lupon said bolt, one ot' which is shown in 'of said wall sections 15 and 16. adjacent said bolt, to permit the retraction ot' the bolt to release said wall sections the oner from the other.

Said shuttle is provided on its forwardl l side wall with a peripheral rim or llangc 2l,

same. dialncter, by which the shuttle is driven when used m the machine, said gear.

of course, being constructed in two sections corresponding to the respective sections -1 and 2, of the hollow' shuttle. Each vot' the respective shuttlersections 1 and 2, are provided with inner peripheral walls 24 and 25, respectively. Y As'shown, parallel guide. rollers 26, are provided near the hinge connection in the inner peripheral wall 25. of the shuttle near the abutting end of said inner walls, and he- ,tween which the paper strip or other wrapping material X, is fed outwardly troni within the shuttle. A filler or bridge member is provided to prevent any portion'of the wrapping material fouling with the opening and closing of the shuttle by becoming `caught between the hinged portions of the shuttle when 'the same is opened. For this purpose a. transverse har or plate 27, is secured flush with the inner wall 25, in close` relation wit-h said guide rolls, and secured thereon is a spring plate or bridge member 28, which extends within the other shuttle section and bears upon the inner surface of y the wall 24, thereof, as clearly shown in Fig. 2, so that when the shuttle opens, the package of wrapping material within the shuttle is supported upon said bridge member. lVithin a compartment or space provided therefor at the end ot theshuttle sec` tion from which wrapping material is drawn, as clearly shown in Fig. 2, is a tension device for the wrapping material, and a folding mechanism for folding the same longitudinally before the material is applied imv to the body being wrapped. V

`Said tension device comprises a spring plate 29, secured transversely in the end of the shuttle section 2, being free at its outer extremity, and pivotally engaged upon a pintlo 30, extending through the side walls of said shuttle section 2, is an adjustable lever 31, the outer end or that directed toward and bearing upon tho `t'ree, extremity of Said spring plate 29, having a roller 32,'

journaled thereon. The adjusting mechanism for said lever 31, comprises an angular sleeve 43, secured to the inner end of the lever into which extends a wedge member 44, comprising a nut threaded on a screw shaft 45, extending through the side walls' of the section and provided with a head at one end shaped to be, engaged b v a suitable tool to rotate said screw to adjust the wedge inwardly or outwardly and thereby swing the outer end ot' the. lever toward or from the spring plate 29.

As shown a lcaf'spiflng 46, is engaged at` its ends on said shaft and bears at lts middle portion against the inner end ot' the levers .and tends at all times to hohl the. inner end roller 32. of the tension device, is the folder for the wrapping material. This comprises,
